What the P0171 code means. The P0171 code means that, on the first bank of the engine, the fuel system is running weak or a vacuum leak exists near this side of the engine. A lean condition occurs when the engine either receives too little fuel or too much air. Apr 6, 2016
Might want to also check you header connections on bank 1.

Hmm thanks for the input! Do you think it’s possible that running e85 could cause an issue? Thanks!
Not sure I understand. You made all these changes I assume to get more performance then say that you "baby" the car every time you drive it and never "beat on it". What am I missing here.

That’s right I baby it on the streets because where I live doesn’t allow me to open her up. Now at the track is a different story.. but I haven’t been there in a while

Definitely check for a vacuum leak. That would be my guess.
With the mods why would you baby it? What's the point of voiding warranty and upping the power without using it?
lol trust me i use it when needed here and there but I wouldn't say that i dog on it 24/7 is what i mean.. That's my biggest fear is it possibly being a vacuum leak. My old 94 Z28 had a vacuum leak lets just say that after playing the guessing game and replacing god knows how many parts it was still present and i gave up. lol

Okay. That makes sense :-) I had this same code in my previous Saleen. It was actually a design flaw in the KB 2.6 Supercharger I had put on. We were able to do a work around in the tune for it though. It was an internal problem with the bypass valve. Was quite annoying until it was figured out. Good luck at finding the issue. I know your pain.
